Description

Technical Field

[0001] The utility model belongs to the technical field of medical treatment, and particularly relates to a laparoscopic trocar assisted puncture hook. Background Art

[0002] A laparoscopic trocar is used to establish a gas transmission channel and a channel for an endoscope and surgical instruments to enter and exit the body cavity from the outside in minimally invasive surgery. The laparoscopic trocar mainly consists of a puncture sheath and a puncture needle. First, the surgeon puts the puncture needle on the puncture sheath, and then applies a certain force to the tail of the trocar. By means of the sharp tip of the puncture needle, the abdominal wall is punctured so that the whole trocar enters the abdominal cavity. Then the puncture needle is pulled out, leaving the puncture sheath as a surgical channel.

[0003] During the use of the existing laparoscopic puncture instruments, there is no protection mechanism, so that when they penetrate the skin tissue, they are likely to cause scratches to the organs or tissues in the abdominal cavity, affecting their use performance. And through the arrangement of ventilation holes, the resistance when the cannula penetrates inside the skin cannot be reduced, resulting in poor puncture effect of the puncture instruments. The main manifestations are as follows: When puncturing the umbilical observation hole, a towel clip is often used to lift the skin, which is likely to cause skin damage. And for abdominal puncture, due to the thick muscle tissue, the puncture resistance is large, the puncture force is large, and after penetrating the muscle layer, it is easy to cause the risk of injuring internal organs because the force is difficult to control, so the operation difficulty is great. Incising the abdomen through the umbilical observation hole is likely to cause the occurrence of trocar hernia. Therefore, it is highly practical to provide a laparoscopic puncture assisted hook that is easy to operate and safe in the utility model. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a laparoscopic trocar assisted puncture hook, aiming at solving the above technical problems.

[0023] Embodiment

[0024] Please refer to Figures 1-4 , a laparoscopic trocar-assisted puncture hook, including two handles 100 and an adjusting mechanism 200. A hook 110 is installed at one end of each handle 100. The two handles 100 are detachably connected to the adjusting mechanism 200. The adjusting mechanism 200 protects the first fixing plate 210 and the second fixing plate 220. The first fixing plate 210 and the second fixing plate 220 are provided with inclined first screw holes 230. A screw 240 is threadedly connected in the first screw hole 230. The screw 240 is threadedly connected to a second screw hole 250 provided at the other end of the handle 100. One end of the hook 110 is provided with a third screw hole 111, and the third screw hole 111 is threadedly connected to one end of the handle 100.

[0025] Specifically, during the puncture process, the user can precisely control the direction and force of the retractor by holding the handle 100 and applying appropriate force. The adjusting mechanism 200 connects the two handles 100 and plays a role in fixing and adjusting. The screw 240 is threadedly connected to the second screw hole 250 opened at the other end of the handle 100, thereby realizing the stable connection between the handle 100 and the adjusting mechanism 200, and also facilitating medical staff to replace the handle 100 with a suitable specification according to actual needs. One end of the retractor 110 is provided with a third screw hole 111 and is threadedly connected to one end of the handle 100, enabling the retractor 110 to be flexibly disassembled and assembled as needed, and at the same time ensuring the stable connection between the retractor 110 and the handle 100. After inserting the retractor 110 into the patient's wound, it can effectively disperse the skin tension, reduce the skin damage during puncture, and also shorten the punching time. The practicability is relatively good.

[0026] In this embodiment: One end of the first fixing plate 210 is fixedly connected with a plug connector 211. A plurality of grooves 212 are formed on the surface of the plug connector 211. One end of the second fixing plate 220 is provided with a plug-in groove 221 sleeved outside the plug connector 211. A manual bolt 222 is threadedly connected to the outside of the second fixing plate 220, and one end of the manual bolt 222 abuts against one of the grooves 212.

[0027] Specifically, by adjusting the insertion depth of the plug connector 211 into the plug-in groove 221, and then making one end of the manual bolt 222 abut against one of the grooves 212 of the plug connector 211, the initial relative position of the two retractors 110 is adjusted. Subsequently, when using the retractor to tighten the wound, an appropriate tension can be provided to the skin.

[0028] In this embodiment: A strip-shaped anti-slip pattern 241 is formed on the outer surface of the cap body of the screw 240.

[0029] Specifically, the provided anti-slip pattern 241 increases the friction force of medical staff when rotating the screw 240, enabling the personnel to quickly adjust the distance between the two fixing plates.

[0030] In this embodiment: A fixing sleeve 300 is arranged on the outer wall of the handle 100, and a plurality of anti-slip grooves are formed on the outer wall of the fixing sleeve 300.

[0031] Specifically, the provided fixing sleeve 300 and the anti-slip grooves increase the friction force of the handle 100, making the doctor hold more firmly and operate more accurately during the operation process.

[0032] In this embodiment: The hook body of the retractor 110 is a curved surface with an inner concave and outer convex shape, and an arc transition surface 112 is provided at the other end of the retractor 110.

[0033] Specifically, the hook body of the retractor 110 is designed as a concave-convex curved surface, which reduces the resistance and skin damage when the retractor 110 enters the wound. The other end is provided with an arc transition surface 112 to provide a smooth transition, further reducing skin and tissue damage and improving the comfort and safety of the operation.

[0034] In this embodiment: the handle 100, the retractor 110, the first fixing plate 210, the second fixing plate 220, the screw 240 and the manual bolt 222 are all cast from titanium alloy.

[0035] Specifically, the selection of titanium alloy material endows the auxiliary retractor with advantages such as high strength, light weight and corrosion resistance, ensuring the durability and long life of the device. At the same time, it reduces the weight of the instrument and the fatigue of the doctor's operation.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
